Siemens HEB1B020B is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in industrial and commercial electrical systems. It features a 20A current rating and a 277V AC voltage rating, suitable for single-phase applications. The compact unit, measuring 200 x 130 x 30 mm (7.874" x 5.118" x 1.181") and weighing 0.661 lb, utilizes a robust thermal-magnetic trip mechanism with long-time and instantaneous (LI) functions for coordinated protection. It complies with industry standards and is engineered for a wide operating temperature range of -25°C to 70°C (-13°F to 158°F). Typical applications include protection for feeders, motors, and branch circuits within panelboards and switchboards.
